[0002] Dehumidifiers are also called dehumidifiers, dryers, and dehumidifiers. They can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers. They are part of an air-conditioned home. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water container, a casing, and a controller. When the dehumidifier is working, the fan draws humid air into the machine, passes through the heat exchanger, and the water molecules in the air condense into water droplets. The treated dry air is discharged from the machine. This cycle keeps the indoor humidity at an appropriate relative humidity.

[0003] The wheel assembly is a key component of the dehumidifier unit. In order to improve the efficiency of the dehumidifier, the sealing of the wheel is the key. Therefore, a dehumidifier unit RWA wheel structure assembly is designed. Utility Model Content

The rotating wheel is also pressed with circumferential R-type sealing strips through R-type sealing strip fixing buckles.

[0007] Preferably, the rotating wheel frame is a sheet metal structure formed by one-time welding, the sheet metal is 2.0 mm cold plate sprayed, and the R-type sealing strip fixing buckle is made of stainless steel with a thickness of 1.0 mm.

[0008] Preferably, the transverse R-shaped sealing strip, the longitudinal R-shaped sealing strip, the oblique radial R-shaped sealing strip and the circumferential R-shaped sealing strip are all made of high-temperature resistant silicone rubber, and the outer wall of the R-shaped sealing strip is coated with a layer of high-temperature resistant and wear-resistant Teflon, and the thickness of the Teflon is 1.0 mm.

[0009] Preferably, the pre-compression amount between the rotating wheel frame and the R-type sealing strip is 2mm-3.5mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the rotor frame of the RWA rotor frame structure of the dehumidifier unit adopts a one-time welding forming technology, which increases and strengthens the strength of the entire rotor frame and reduces the material cost. The sealing method of the rotor completely abandons the traditional sealing method of the dehumidifier unit rotor, designs an R-type rotor sealing strip structure, reserves mounting holes on the rotor frame, and fixes the R-type sealing strip fixing buckle by riveting.

At the same time, this structure provides great convenience for the maintenance and maintenance of the rotor in the future. BRIEF DESCRIPTION OF THE DRAWINGS
